buy despite a number of negative criticism ...

... And satisfied. Finally, you also have the price in relation to the goods see .. pure copper cable's now so expensive that it is really poor in larger "laying routes". I have simply a larger cross section selected as required and therefore the losses reasonably balanced .. going .. and it was still cheaper in cost than with pure copper cable ..
Oh yes, and then there was the criticism of the "stiffness" of the cable:
ok - it's definitely a bit stiffer than copper cables - added - but this is still not really an issue .. one can exaggerate everything ..
I have the cable for my hi-fi speakers "Surface" laid on the floor base and then simply painted over with dispersion in the same color as the corresponding walls ..'m happy .. happy again (for the price !!!!)
